The IC3600AFGA1C1 is a GE FANUC PCB designed as a Function Generator Board for the Mark I or the Mark II series. The MKI was released by GE in 1969, and the MKII in 1973. Both systems have operating temperature ranges from -50 degrees Celsius to +50 degrees Celsius. The MKI and MKII can manage heavy-duty turbines rated from 4000 hp (individual) to 400 Mw (combined cycles). The two series are built to achieve high performance, accuracy and a quick response time, using electronic computation and high-resolution servos. The IC3600AFGA1C1 is drilled for mounting in two corners. One edge is numbered (ten to forty) by tens. The numbering corresponds to twenty-five individual metal pins attached to the board’s surface. These right-angled metal pins face outward toward the edge of the board. The IC3600AFGA1C1 is marked with its unique board number, with the GE logo mark, with the code ‘006/04. ‘It is marked ‘AB’ in one corner. Most components are marked. The IC3600AFGA1C1 is built with two integrated circuits and twelve transistors. The circuits in this board are both amplifiers with low current error. The transistors used in the board are primarily designed for small-signal-medium-power applications. The IC3600AFGA1C1 has a set of spare PTH (plated through-holes,) two potentiometers, and many resistors, diodes, and capacitors. Capacitors may be ceramic or polyester vinyl. Resistors are primarily five-band fixed carbon film.
